The present invention relates to a volume change heat dissipation system, and more particularly to a crankshaft that is driven by the swing mechanism to push the crank, and the crank pushes the deflector of the flow guiding device disposed at the upper end of the linkage rod to move up, and The hot air trapped in the casing is sucked into the air chamber through the check film provided by the air intake device, and cannot be returned to the casing, and the crank pushes the flow guiding device disposed at the upper end of the connecting rod When moving down, the hot air is discharged from the exhaust port provided by the air chamber to achieve the heat dissipation and energy saving effect.

According to the computer system, it is widely used in human life. The main computer mainframe includes an external casing and electronic components such as a motherboard, a memory, a central processing unit, etc. installed inside the casing. The metal plates are simply assembled with each other to form a box or box having a storage space therein, and the main purpose thereof is to prevent foreign objects from colliding or abrading to internal electronic components.

Since the aforementioned electronic components are operated by electric energy, the more complicated electronic components in the computer mainframe, such as the central processing unit, generate a large amount of thermal energy during the operation, and the thermal energy gradually accumulates and gradually increases the temperature of the electronic component. The thermal energy cannot be continuously removed, which may affect the efficiency of the operation of the electronic component and even shorten the service life of the electronic component; The cooling methods are water-cooled and air-cooled. The water-cooled heat-dissipating system is expensive and the installation technology is high. The air-cooling method is cheap and easy to install. The traditional air cooling method is to add a fan, and the heat dissipation effect can be achieved by the size of the fan, the size of the fan, and the position of the fan.

In the prior art, patents related to air-cooling heat dissipation are as follows:

1. For example, the invention patent No. I373598 "Hot Exchange Ventilation Device" announced on October 1, 101, the invention patent, which uses the air supply blower to take in outdoor air from the outdoor side suction port and pass through the heat exchanger. The air-to-heat exchange passage, the air supply passage from the indoor side outlet air supply to the indoor air, and the indoor air intake from the indoor side suction port by the exhaust air blower, and the exhaust heat exchange passage through the heat exchanger from the outdoor side The exhaust passage that blows the outlet to the outside is formed in a heat exchange ventilating device in the outer casing to achieve the effect of heat dissipation.

2. For example, the new patent of M743603 “Computer Case with Ventilation and Heat Dissipation Effect” announced by the Republic of China on September 11, 101. This new patent utilizes the first and second outer plates of two sheets and several pieces. a computer case assembled by a plate, a root sleeve and a plurality of guide columns, and the computer case assembled by the sheet-like plate is emptied up, down, left and right for cooling and cooling effect of the computer case .

Furthermore, patents related to water-cooled heat dissipation are as follows:

1. For example, the invention patent No. I323403 “heat-dissipating case” announced on April 11, 1999 of the Republic of China, which includes at least two heat-dissipating modules for circumferential molding, each of which includes two water collecting tanks. Folding a plurality of circulating tubes connected between the water collecting tanks, and a plurality of heat radiating fins disposed in parallel and spaced apart from the water collecting tubes, wherein the water collecting tank and the circulating tubes are The portion is filled with a heat-conducting fluid; by circulating the heat-conducting fluid, the cooling surface can be attached to the surface of the electronic component to quickly absorb the heat generated by the operation of the electronic component, and conduct the heat to the heat-dissipating fin to achieve heat dissipation. The effect.

2. For example, the new patent of M356950, “Improvement of water-cooling and heat-dissipating structure of computer mainframe” announced by the Republic of China on May 11, 1998, the new patent system includes a computer main body having a casing, and at least a main board is provided in the casing. a storage unit, a power supply, a connector, and a plurality of electronic components, and the rear end of the casing is provided with a plurality of perforations; a receiving unit disposed in the casing and corresponding to each of the perforations; and a housing disposed in the receiving unit The water cooling mechanism has at least one cooling unit corresponding to each perforation of the rear end surface of the casing, at least one heat absorption unit connected to the cooling unit and attached to the main board, and a supercharging unit connected between the cooling unit and the heat absorption unit. And a gas guiding unit corresponding to the other end surface of the cooling unit to achieve the effect of heat dissipation.

However, according to the above, it has the following problems:

1. The invention patent of "heat exchange ventilator" No. I373598, which is useful for heat exchangers, however, the use of heat exchangers has the problem of different wind speeds at the inlet. Therefore, the air supply and exhaust paths are provided at the convection of the heat dissipation, so that the air flow speed is accelerated and averaged, and the heat dissipation efficiency is increased. However, due to the installation of the heat exchanger and the fan, the internal space of the computer is easily insufficient.

2. For example, the new patent of M743603 "Computer case with ventilation and heat dissipation effect", this patent is made up of a combination of a metal inner plate and can not be added with a fan, so the heat dissipation is the use of natural convection. The way, the heat dissipation effect is better than the fan blow effect. Poor; in addition, because it is a bare metal, if there is liquid spilled into the case, the computer will be damaged.

3. For example, the invention patent No. I323403 “heat-dissipating case” announced on April 11, 1999 of the Republic of China is composed of a fully ventilated metal circulation conduit. The metal conduit is provided with a heat-conducting liquid conveyed by the water collecting tank to dissipate heat. Since it is a metal conduit, there is no need to worry about a tube explosion problem. Although it is not currently on the market, it can be expected that the price should be very expensive; in addition, it is a full bare metal design, in case of accidental liquid spillage, it will cause damage to components.

4. For example, the new patent of M356950 “Improved Water Cooling Structure of Computer Main Unit” announced by the Republic of China on May 11, 1998. This patent integrates the casing with the water cooling system, and the heat dissipation is by water cooling. The heat is dissipated, so it is not necessary to use a fan, and it can be dustproof. However, the disadvantage is that the computer will be damaged if the draft tube is squished, and the cost is high.
